Truly, the most important long term factor that should be considered when choosing a foundation waterproofing contractor is the warranty issuance and what that may mean in the long term.

In the last five years we have noticed that everyone with a pickup truck and rubber boots is now a waterproofer. This trend comes and goes every few years and coupled with misdiagnosis, improper repair and materials approach and poor quality workmanship the individual who pays most for this unrelenting market saturation is you, the customer. Every year or so, Google becomes populated with a plethora of contractors and family run businesses all of which have been waterproofing for a century while carrying 90 year warranties, and so on.

Let’s face it, you get what you pay for. Complex waterproofing and drainage considerations coupled with a high degree of difficulty and slim margins for error usually drive these fresh contractors out of business in a very short period of time. The end result? They close their doors and shut off their phones, leaving their warranty void and the customer stranded. Beware of empty, long term warranty promises and fly-by-night contractors.

Waterproofing and drainage considerations throughout the province haven’t changed in decades (albeit more is now required) but nearly every trade show we attend is full of new products, materials and techniques for cheap and quick waterproofing and structural repairs. Trust me, if there was an easier way aside from complete excavation to establish a true lasting warranty, we would know about it! The residential waterproofing industry has quadrupled in product scope and size throughout the last ten years and now even the big-box stores carry plastic sump pumps and low quality rubberized membranes. Remember, in this overly saturated industry you are purchasing peace of mind in the form of a dependable, long lasting and guaranteed warranty process.

So you can trust in our experience, process and expertise because this is truly all we do.
